The 'invention relates to hair waving appliances, more particularly having reference to hair heating unit's'for use in hair waving and elements for heating the units.

In the art to-Which the invention relates it has been proposed to provide heating units of this character comprising elements co-operating to provide a channel for reception of hair and heating means for the units, the heating means more 10 usually being either in the form of an electric heating element insertable within the channel of the unit or embodied in the unit itself. The present invention contemplates certain improvements in hair waving appliances of this character, one of the objects of the invention being to provide an improved heater in the form of an electrically heated device apart from the units by which the units may be quickly and conveniently heated, and a cabinet mounting the heating elements providing compartments in which the hair waving units may be received to be heated.

Other features and advantages of the invention will become apparent by reference to the accompanying description taken in conjunction with the drawings wherein like characters of reference indicate like parts throughout the several views and wherein:

Fig. 1 is a perspective view of a cabinet embodying the improvements, the lid of the cabinet being shown open and a hair waving unit disclosed in one of the heating compartments.

Fig. 2 is a detail side view of an assembly of heating element, frame, heating compartments, 85 and thermostat, the whole assembly being shown as removed from the cabinet.

Fig. 3 is an inverted perspective view of the parts shown in Figure 2 but with the heating element removed from the frame.

Fig. 4 is a detail end view of the heating element.

Fig. 5 is an end view of a hair waving unit, the same being partly sectioned and broken away to disclose the spring and handle mountings.

Fig. 6 is a side View of a hair waving unit.

Fig. '7 shows a side view of a pair of tongs for lifting and applying the hair waving unit.

Having reference to the drawings there is shown a cabinet I of conventional design within 60 which the electrically heated plate for heating the hair waving units is mounted. The cabinet includes a cover 2 which may be hinged to the body of the cabinet and includes side supports in the form of slide members 3 for supporting the cover in open position. The cabinet further ineludes drawers 4 as indicated and slide out door 5 for covering the drawers when the cabinet is closed to make a compact portable outfit.

Within the top of the cabinet is mounted a frame 6 carrying the various elements comprising the heating apparatus and thermostatic control. This frame is secured within the cabinet by screws through the cabinet wall, as at 1, and by a flange 8 at one end adapted for support on a suitable cross member in the cabinet, not shown, to 10 which the flange would be secured by screws 9.

The frame 6 and associated parts and elements may be more clearly understood by reference to Figures 2 to 4 inclusive.

Attached on the under side of the frame 6 is u the heating device. This includes a sheet metal cover In providing depending flanged sides ll engaging an insulating base l2. Openings are shown at I 3 through the cover and base and complementary-openings I4 in the frame 6 by which 90 the whole may be secured together by bolts or the like.

Between the cover In and base I 2 is mounted a continuous heating coil IS, the coil being spaced from the cover by a mica sheet I6. In association with this coil are the terminal contacts I1,

18 and I9. A series of bolts 20 are included in the assembly to hold the cover and mica sheet flat.

The frame 6 includes two openings at 2l2l defined by turning the marginal portions of the frame, indicated by numerals 22 and 23, downward to provide in conjunction with the flat cover of the heating element compartments for heating the hair Waving units.

The frame 6 further includes a section at one end divided from the remaining portion of the frame by an asbestos wall 24. In this section or compartment is mounted a thermostat control for the cabinet, this being generally indicated by numeral 25.

This control is of a design common in the art to which it pertains and includes a bulb 26 located between the compartments 2 l-Z I, the bulb being supported on and protected by an asbestos filler. Liquid in bulb 26 passing through a capillary tube 21 would actuate a diaphragm in the control mechanism of the thermostat.

The thermostat element includes a control dial 28, neon pilot light 29, and receptacle 30 for lead wires 3|, 32 through the thermostat and 33 for the terminal contact l1, wires at 34-35 being provided for the contacts l8-I9 to the thermostat. There is also shown a ground wire 36.

Each of the hair waving units to be used with the improved heater, (see Figures 5 and 6) would include mating unit members or halves 3'!31 that cooperate to define a channel 38 for reception of hair to be treated. The unit members would include essentially flat under sides to rest on the heating surface of the heating element in the cabinet.

The members 3l3l are held together in working relation by springs 39 inset in suitable transverse openings 40, these springs at the same time forming a pivotal connection between the unit halves. The springs 39 are engaged at their ends by handles 4|, the handles being in the form of bent wires the ends of which are received in suitable vertical sockets in the unit halves, the vertical sockets disecting the openings 40.

For lifting the hair waving units tongs or the like would be provided, these being separately illustrated in Figure 7 and include cross pivoted handles 4242 urged together by a spring 44 and providing jaws 43--43 for engagement of the handles.

The hair waving units would be placed in the heating compartments 2i as shown in Figure 1 where a unit is indicated by the numeral 45.

The fiat under surfaces of the units are designed to intimately contact the cover ID of the heating element and readily absorb the heat therefrom in addition to which the compartments form highly heated areas.

The use of the improved heater and hair waving units provides a very economical way of heating the units and particularly provides a unit that will retain the heat well. Uniformity of heating is obtainable, the thermostat element in control permitting, by setting the dial 28, determining and maintaining a constant uniform heat in the cabinet, this being very valuable in obtaining uniform results in the treatment of hair.

While we have herein described a preferred embodiment of the invention it is obvious that changes in parts and elements would be permissible and such changes would be considered as anticipated by the invention in so far as they I come within the scope of the appended claims.

What is claimed is:

1. A hair waving unit comprising a pair of cooperating unit halves recessed to provide a channel therebetween for reception of hair to be 10 treated, said halves each providing transverse openings spaced apart, the openings in opposing halves being alignable, coiled springs inset in the openings, and a handle for each half, said handle providing a pair of legs, and the unit half 15 providing downwardly directed openings intersecting the transverse openings in the unit halves, the legs of the handle being insertable in the downwardly directed openings and engageable with the spring ends to hold the assembly together.

2. A hair waving unit comprising a pair of cooperating unit halves recessed to provide a channel therebetween for reception of hair to be treated, said halves each providing transverse openings spaced apart, the openings in opposing halves being alignable, coiled springs inset in the openings, and a handle for each half, said handle being in the form of a drawn piece of metal bent w to provide a pair of legs and an intermediate hand grip, the unit half providing downwardly directed openings for reception of the handle legs, said openings intersecting the transverse openings in the unit halves, the legs of the handles providing transverse openings through which the spring ends are insertable for engagement therewith.
